This invention relates to alawnr sprinkler yoi that class whereinthe. sprinkler head is rotatably `mounted on' the' .upwardly turned end of a water vdelivery pipe mounted to moveradially about a centre, to which the water is delivered the outer` end of which radialpipe adjacentthefsprinkler heard is` 4supported on a wheellwhich is Vdriven by` gearingifrom the, rotationfot vthe sprinkler head. f' l v i TheA improvements. are directed to the piv-` otal connection-of theradial pipelto thecen-` tral support thereof. #To the provision of' a lsupplementary `water' spraying nozzle angu larly projecting upward .and outward-from the upwardly turned endA of thepipe, onf

which the sprinkler head is moui'ited,l and to a double drive," for the supportingv Vwheel where the water pressure ymaybe low.

There are'other Yfeatures yof improvement to which attention is drawn in the following f specilication, which fully describes the vdevice, reference .being made to the drawings by which Sit is. accompanied, in which:

Fig. 5 is an enlarged detail of the central Pe y In these drawings 2 represents a short central pipe which is supported with its anis substantially upright in a cross shaped stand 3, being secured in the stand and thetwo parts of the stand secured together` by a nut 4 threaded on the pipe 2 and an elbow 5 threaded on the lower end ofthe pipe 2 to receive the connection .of the hose pipe 6 through ywhich water is delivered to the sprinkler from any convenientsource.

Rotatably litting this central pipe2-is an inner pipe 7 :tormingthe stem about which the sprinkler rotates.

outer end of 23 so asto project a spray from y the fixed nozzle 21 outward beyond the range of that from `the sprinkler head: Or, as Shown in Figure 4, the nozzle cine 21 may be secured to ,theup'per end of the pipe 11 on which the "sprinkler head rotates.`

Although 'in Fig. 11 of the drawing, the uptake pipe vll'is shown outside the sup'- 4porting wheel 10, where the pressure of the water supply 4is vlow and the supply ample, a

parallel pipe 22 may be connected tothe y radial pipe 9 as a branch within the supporting wheellOvand a second sprinklerl head mounted on it withthe pinion 14X of the sprinklerv head meshing with the wheel 15 on the d'iametrically opposite side. The pinion 20 which `drives the` 'supporting wheel lOmayb'e secured `on the underside of the stem 16 of the wheel 15., sothat both sprinkler heads act to drivethe supporting wheel through the same intermediate wheel` and pinion.

The'devlcewill automatically sprinkle an i 10 1 `area vconsiderably beyond the range of the invention,`we hereby declare that what we' sprinkler head 12 as it travels slowly round the circle on its track wheel 10, as the jet projected from the nozzle 21 as it moves round the circle, will throw its spray considerably beyond that of the sprinklery head 12, whether that nozzle 21 is mounted on the upright pipe 11 which directly serves the sprinkler, or, as shown in'lTigs. 1 and 2, on the end of the extension 23 'from the pipe 9.

The speed of rotation o t the supportingl wheel 10 being reduced considerably from that ott the sprinkler head which supplies the power, the track wheel can surmount any ordinary obstacle, such as the hose pipe which serves the sprinkler. o

Havingy now particularly described our claim as new and desire to be protected in by Letters Patent, is:

1. A traveling lawn sprinkler, comprising in combination a stand to theI centre of which a water service is connected, a radial pipe one end of which is pivotally connected to the water service of the stand `to rot-ate around it, an upwardly projected pipe sec tion carried on saidy radial pipe adjacent'to its other end, a supporting wheel rotatably kmounted on the radial pipe, a reaction sprinkler rotatably mounted on the said upwardly projected pipe section the hub of said f sprinkler being formed with teeth as a pinion, means for rotating the supporting wheel at a reduced rate of speed from the sprin kler, and a jet nozzle -fixed in the-end ot the radial pipe to deliver angularly outward and'upward therefrom.

` 2. A traveling Alawn sprinkler 'comprising a stand, a central pipe vertically secured on the stand, an inner pipe having a collar at its lower end, .which pipe is rotatable in the ,central pipe with the collar seating against the inner end thereof and the upper end passing gland-packed through the upper end of the central pipe, a water service connected a stand, composed of two strips of relatively thin metal medially apertured and downwardly bent toward their ends, a central pipe securing the two strips 'together to i form a cross shaped stand, an inner pipev roj tatably iitting the central pipe and having a collar at its lower end fitting against the en@L of the pipe,` the upper end passing gland-packed through the upper end of the central pipe, meansv tor delivering a water service tothe lower end of the central pipe, a pipe secured to the upper end of the inner pipe to move radiallyvaround it, an upright pipe connected to this radialpipe intermediate its ends, a track KVwheel mounted adjacent the upright' pipeLa reaction sprinkler rotatably mounted on the `upwardly turned pipe, means for rotating the track `wheel at a reduced rate of yspeed* tromthe hub of the sprinkler and a nozzle projecting` angularly outward and upward fromv the free end of the radial pipe. 'A l In testimony whereof we atiix our signatures.
